Adele's All I Ask covered by Bruno Mars

During their stop in at the BBC Live Lounge, Mars and Co. gave the 25 ballad “All I Ask” a spin in their own speed. There’s definitely a hint of the early ’90s with the keys lying underneath Mars’ voice, which manages to make the key change at the very end. “This next one I’m about to do for y’all,” Mars said before starting, “is a song that means a lot to me.”

Before slamming the mic to the ground, Mars honored the pop star he just covered: “We love you, Adele!” he yelled.

The “Uptown Funk” singer is making the rounds to promote his new album, 24K Magic, due Nov. 18. Mars appeared on Saturday Night Live on Oct. 15 and played the title track and debuted a new one, “Chunky.”
